A lock-up is additional to a normal clutch operation. The springs provide some force to start the effect. The weighted arms are mounted to the transmission input shaft(clutch inner hub) so do not spin when the bike is stationary. On clutch drop especially with the normal "weak" springs,the clutch slips some,versus the tire. As the bike begins to move the weights now begin to apply centrifigal force to add to the springs and make the clutch stop slipping,ie "lock-up". (stolen from "Dragbike.com")

Since these bikes were never used for drag racing, the likelihood of finding a lock-up clutch is practically nil.

Usually the opposite is what was in demand for track use, a slipper clutch (or more accurately, a back-torque limiter) that removes clutch spring pressure during deceleration to prevent rear wheel lockup during braking.
